This article is centered around the question of whether or not
it's time to upgrade a PC's OS. It gives Linux and WindowsXP
generally equal billing as options, mentions the BSD's briefly, and
comes down on the Linux question:
"Linux users face the opposite problem, with several
different word processors, spreadsheets, e-mail and drawing tools
The problem is finding out which ones will work with on files
created by colleagues still using Windows.
Linux does not run familiar Windows programs by itself, though
it is possible to run them via an emulator, or to use programs like
StarOffice that read Word or Excel files.
Despite all the improvements, installing Linux still takes a
little technical courage, though the benefits in terms of learning
how your machine works can be substantial."
